Eosinophilic granuloma of the orbit: report of two cases.

摘要

We present clinical, radiological, and histopathological findings and treatment results of two infants with orbital eosinophilic granuloma. Both patients presented at 1 year of age with unilateral proptosis, periorbital edema, and a superotemporally located, ill-defined orbital mass on computed tomographic (CT) imaging, with bone erosion in one patient. After subtotal excision, histopathological examination revealed eosinophilic granuloma, and the proptosis resolved with no sign of orbital tumor recurrence or systemic involvement at 12 and 23 months follow-up. Eosinophilic granuloma is a rare childhood orbital tumor that may or may not present with osteolytic change.
